Right now, if I include any kind of website link or URL in a message to someone, it creates a preview of that site or page. I know hard work went into that feature, but it is terrible in many contexts.
The included screenshot shows the problem -- and in fact fails to even preview a legit site.
I would much prefer for that sentence to be:
He was going to artonomo.com and should instead be going to jewelbranding.artonomo.com. That should solve the login problem.
(Where you would have the sites linked, if you like.)
In any case, this should be a user-specific preference because some people like previews, and some do not.
Personally, I view those kind of previews as the purview of less business focused apps like Discord, but to each his or her own!
